Your TV sucks! (Wrong aspect ratio and shape)

[bhampton]

Curved screens will have distorted geometry unless it's corrected via software.

Anyway, get a projector and you can have any aspect ratio and curved screens too.

Or just wait, new products happen maybe you will get the thing you want.

Problem solved, 57" Samsung monitor that's 7,680 x 2,160 31:9. You'd probably have to watch everything from your PC and sit a few feet away, but the World's your oyster. Of course it's overkill, but they do narrower monitors, but I think this is the biggest.

If you like watching everything pillar boxed, here's your dream display. Pretty aggressive curvature on this monitor (1000R), too.

I think it would be neat to experiment with, it's basically the height of a 32" screen and almost twice the width. If the black levels are decent and the local dimming can get rid of the pillar-boxing it would be neat.

Like we've said there is no perfectly sized display unless manufacturers come up with a viable adjustable screen, and it would need to be much bigger.

I would enjoy playing with it as a gaming monitor, but not as a display to watch movies or TV shows with. The curvature on this monitor seems a bit extreme.

I use two 32" 1440p curved monitors for my computer, but the curvature radius is much more subtle at 1800 mm.

Too extreme. I get sick just looking at them. Like I said, the curve needs to be really subtle. Like my monitor's.



But the distance from a monitor reveals too much detail. You see the grain too well, on top of all the compression artifacts and digital muck. Tried to watch Miami Vice on the computer last night and just couldn't. They're not good looking discs, but on a monitor they look like shit.

Again, place black behind the OLED/MicroLED. You will never see black bars again. Most TVs have black bezels.

Black bars don't bother me. I am long accustomed to their presence. I do not even think about them when I watch something.

I'm curious how you determined this. Did you use the required Craftsman model 1019 Laboratory Edition Signature Series torque wrench? The kind used by Caltech high energy physicists and NASA engineers?

It's just simple geometry.

One thing is that it may not be perceived but it's there. The brain adapts and gets used to it as normal. It also depends on the size of the screen relative to you (field of view). If the screen is small or you sit far away it's less noticeable. But the distortion is there as you are farther away from the edges than to the center. The farther a thing is the smaller it "becomes". It's called barrel distortion. Here's it drawing that depicts it so it's easily visible:

To counteract it you do the opposite, called pincushion distortion.






The simplest way to do that with screens is a curved screen.




The above is for people sitting on the center in front of the screen. People sitting offscreen or to the sides get it worse cus now the far end of the screen can be near double the distance that the left and right sides of the screen are for someone sitting in the center.

A curved monitor also helps in this, as the far side curving inwards works better than with a flat movie screen/monitor, like this:

|
v


|
v

Home or Cinema, the curved screen works better for the far range ends of the screen.

Also as the curved screen edges are closer, encompassing you, a curved screen can look bigger than a flat screen of the same diagonal size specially on Scope movies at the proper distance. My 65" curved screen looked more to equivalent of a 67" flat screen with them.



Many people sit far away from the screen and they perceive this less or are used to it (the brain is an incredible thing) cus they're looking at the movie in postage stamp size comparable to the last row of a theater, versus to how they were made to be seen.

Typical home viewing, 4PH (picture heights) from 16:9 screen, 5.33PH from Scope movie (ex: 10'/3m from 65", or last row of the theater)



Middle of theater, 2PH.





About curved theater screens' existence, the premium theaters had curved screens, I saw a lot of the 70s and 80s blockbusters on them (Star Wars, Indianas, Alien, Supermans, and what not, even Basic Instinct in a new curved screen on a new multiplex (that still exists) so they were being projected in them still. But is easier (cheaper) for a theater to make a flat screen for a flat wall, and that is the game of the multiplex. But I ocassionally see movies on curved theater screen, like the J.J. Trek on curved IMAX, and other newer “IMAX” presented movies.

Is this really a problem?


(The answer is No.)

[Deciazulado]

To me it is because I want a new curved UHDTV screen and I can't get one.

So is this a problem

Yes.

When I asked on AVSForum a few years ago, I was informed of a pincushion option that can be modded into MPC-HC. I never did end up watching a movie with it because it would have meant moving my seat closer and calibrating the speakers again, for just 2.4:1 movies, while narrower than 1.78 movies would have been too small. If TVs had a customizable pincushion option just built in, I'd get a bigger TV than I normally need and only use the top and bottom of the screen for the sides of the 2.4 and wider picture, where the black bars finish curving up/down to the frame.

Thank you for the detailed explanation and for the demonstration of flat screen distortion.

However, if a person can not perceive this distortion in practice, i.e. watching movies on a flat screen TV, and they also can not do anything about it because there are no curved screen TVs on the market, then that kind of limits their options, doesn't it?

I do not perceive this distortion when watching a movie on my flat screen 85" TV at a distance of 8-8.5 feet. My TV screen is at eye level with no need to crane my neck upwards and I sit directly across from the center of the screen.

I would wager that extremely few people perceive this flat screen distortion, either. Until coming across this thread I have never once heard of anyone complaining about flat screen distortion on their TVs.

I would say with confidence that this is a non-issue for almost everyone for two obvious reasons: most people do not notice this distortion and they can not do anything about it even if they did- unless they want to go the projector route with a curved screen and all of the expense and logistical problems that entails.

Some TV manufacturers offered curved screen TVs in the past and their discontinuation demonstrates that there was not enough demand for them.

[Warm Gun]

Yes, you do perceive it.

It is pretty arrogant of you to say that you know what other people perceive.

If I perceived flat screen distortion, I would actually care about it. As I do not perceive flat screen distortion I do not care about it.

I suppose you are going to tell me what I care about next.

If most people perceived flat screen distortion then they would have bought curved screen TVs when they were available. They did not buy them and thus they were discontinued. Which is more likely: that most people did not notice such distortion or that they did notice it and chose to buy flat screen TVs anyway, in effect saying that they prefer distorted images?

Even Deciazulado said this:

Be sure to correct him, also.

The bottom line, for the umpteenth time, is that whether or not people perceive flat screen distortion, there is nothing that anyone can do about it if they want a direct view display. The two of you that do care about curved TVs so much should try your luck lobbying the TV manufacturers to bring failed curved screen TVs back to the market. Best of luck with that.

[Warm Gun]

Well, then try a curved screen for a while and then go back, because it's really ****ing obvious, was obvious to me even before I got this curved monitor, if not by perception than by, like he said, basic geometry. Which is why to say one can't see it seems like dishonesty to me. We make excuses for many things, understandably.
